Specification of Letters Patent.

Patented March 17, 1908.

Application filed July 10, 1907. Serial No. 383,063.

'exact description thereof.

The object of my invention is to provide a simple, economical andefficient separator for )ulse, berries or the like.

The invention is particularly designed for cleaning hulled peaspreparatory tocanning, the same being passed through the machine toseparate the sound eas from those that are split or flat, toget er withany foreign substance.

Said invention therefore consists in certain peculiarities ofconstruction and combination of parts as hereinafter fully describedwith reference 'to the accompanying drawings and subsequently claimed.

In the drawings: Figure 1 represents a side elevation of a separatorembodying the features of my invention, parts being in section and otherparts broken away to better illustrate the mechanical details; Fig. 2, adetail section plan view of the screening-end of the machine, thesection being indicated by line 2-2 of Fig. 1; Fig. 3, a cross-sectionon line 3-3 of Fig. 2; Fig. 4, a detail section on line 4-4 of Fig. 2,and Fig. 5, an enlarged cross-section of a portion of the belt,illustrating the referred formof pins theref securing the same.

Referring by numerals to the drawings, 1 and 2 indicate front and rearstandards respectively of a suitably braced frame, between whichstandards are fitted side-boards 3 connected by brace-strips 4. Thesideboards and brace-strips constitute a skeleton trough'that is pivotedto the rear frame standards 2 by a rod 5 and nuts thereon, which rodpasses through the standards together with said side-hoards. The troughis adjustably set and held at an inclination by means of strips 6, whichstrips are pivoted to the front standards 1 and are slotted for thereception of bolts or studs 7 that project from the trough, the saidbolts being threaded to receive suitable clamping-nuts 8 that bind theparts together.

The front or lower end of the trough has secured thereto a chute 9, uponthe inclined trough and near the front end thereof.

bottom 10 of which the cleansed peas are delivered from an endless belt11, the construction and arrangement of the belt being hereinafterdescribed. Intermediate of the trough-ends and secured to the upperedges of its side-boards is a hopper 12, having a feed-opening 13therein, the area of which feed-opening is adjusted by means of a gate14, there being a threaded stem secured to the gate and inthreaded-connection with an adjusting-wheel 15, the same being confinedby a bracket 16 secured to the hopper-wall. Spindles 17 and 18 ofrollers 19 and 20, are j ournaledin boxes 21, 22, respectively at theends of the trough, the rear box 22 which carries the spindle of roller20 being adjustable for the purpose of regulating the tension of theendless belt 11, which belt is mounted upon the rollers. Roller 19 ispreferably an idler while roller 20 is driven by a pulley 23 fast on itsspindle, the opposite end of the spindle being provided with asprocket-- wheel 24 that is in link-belt connection with a smallersprocket-wheel 25 of a shaft 26.

This shaft projects through vertically dis-' beater is arran ed tocontact with the lower or slack side of the belt, imparting to said belta'vibratory motion similar to that described in connection with thefirst mentioned beater. The beater 30 is driven by a sprocket-wheel 32fast on its shaft and in link-belt, connection with a sprocket-wheel 33secured to the idle-roller spindle.

The endless belt 11 is preferably composed of layers of canvas stitchedtogether and is provided with series of rows of headed pins 34, whichpins project throu h the canvas. Theshanks of the pins, direct l yadjacent the canvas, through which they project, are provided witha'series of burs 35, which burs extend only for a ortion of the lengthof the exposed pins, and serve to catch any small particles of trashsuch as leaves, thistles,

This

etc., the pins being positioned in rows so that they are staggered withrelation to the next adjacent row. i

To prevent the material which is fed upon the belt from dropping betweenthe edges of the same and those of the trough side-boards, the latterare provided with valance stri s 36 of rubber or other suitablematerial, tfie free edges of said strips being positioned so that theywill hug the upper face of the belt just inside the' lines of pins,t-hus effectually sealing the joints as best shown in Fig. 3 of thedrawings. S In the operation, theupper or workingface of the belttravels upgrade, (as indicated by the arrow in Fig. 1) and as the peasare fed from the ho per, those which are smooth, sound and perfect, willgradually find their way through the maze of pins to the chute and .bedischarged, traveling by gravity in the opposite direction from that ofthe belt.

Should any of the perfect peas be caught by the pins, they will bedislodged by the vibrations of the beater 29 before said eas could passover the rear end of the elt. The broken split or fiat peas howeverwould not roll down the inclined belt, but would becaught by the sharpburs of the pins as a would also any foreign substances such as upperroller 20.

leaves thistles, etc, and be carried up with the traveling belt untildischarged over the Such trash as would not clearby gravity from theinverted belt-pins would be shaken from the bottom or slack side of thebelt by means 'of the beater 30, after which said pins pass over' theidleroller and upward. The beater '29 being adjustable, may. be set soas to produce a greater .or less degree of vibratory motion to the belt,it being positioned in proportion to the inclination of the belt and thecondition of the material being cleaned.

While I have shown and described minute details of construction ascarried outin the drawings, it is understood that the structuralfeatures. -mentioned form no part of my invention, except as far as theypertain to a practical device, the essential features of which are thesuspended inclined belt traveling up the inclinationand having apin-surface, together with means'for imparting 'vibratory motion-to thebelt. It is also understood that in some instances if desired, the headsof the belt-pins may be covered or backed up with another layer ofcanvas to add rigidity to same.

To com lete the cleaning process, it has beenfoun desirable to discharethe screened peas upon an endless sortingelt 38, which clined endlessbelt, having pins extending therethrough provided with burred shanks, afeed-hopper over the upper stretch of the belt intermediate of its ends,and a beater adapted to oppose the inner surface of said upper beltstretch located intermediate of the feed-hopper and the upper terminalof the belt.

2. A se arator comprising a driven inclined en ess belt, having pinsextending therethrough provided with burred shanks, a feed-hopper overthe upper stretch of the belt intermediate of its ends, the material fedbeing delivered by gravity over the lower terminal of said belt, meansfor driving the upper stretch of the belt in the opposite direction fromthe gravity-flow of the material, and a beater adapted to oppose theinner surface of said u per belt stretch located intermediate of thefeed-hopper and the upper terminal of the belt.

I 3; A. separator for pulse or the like comprising a frame, an inclinedskeleton trough hung in the frame, means for adjusting t e troughinclination in connection with the frame, a feed-hopper above the-troughintermediate of its ends, rollers journaled in the trough-ends,driving-means for one of the rollers, an endless belt carried by therollers, a series ofpins projecting from the belt having burred lowershanks a revoluble beater journaled in the trough adjacent to its highend and arranged to oppose the inner surface of the upper belt stretch,driving means for the beater, a second beater journaled in said troughand arranged to oppose the inner sur face of the lower'belt-stretch, andmeans for driving the second beater.

In testimony that 1 claim the foregoing I have hereunto set my hand atTwo Rivers in the county of Manitowoc and State of Wisconsin in thepresence of two witnesses.
